I am trying to live map my Cosworth 4x4 redhead and have got a definition file which is IAW048_01.xdf and I have just learnt that the definition file that I have is for a catalytic converter green head, the one I need apparently is IAW048_02.xdf. Does anybody have one or is there a difference between the two files and could I live map using the catalytic converter file. I realize people are reluctant to give these away but I am hardly a threat by way of competition as I am in the middle of Canada and there are probably only 10 Cosworth in the country.Thank you to anybody that can help me

 

contact msd with ya spec and they will send u a chip pall. job done and no messing about..

 

I've got a chip I need a file

 

Contact flux capacitor on here, he loves giving away other peoples hard graft apparently

No tuner is likely to send you out a free file IMHO

 

Nobody said I wanted it for free, I just need help stuck in the middle of Canada where nobody can spell Cosworth let alone drive one!

 

As above then, just order a chip with the correct file on it from MSD.

 

The software will be different but I assume from what you want you have a standard car?

They are very easy to change, however to live map I think you will need a emulator etc?

Have you tried opening your bin file with the IAW048_01 definition? If the values all look like junk then you'll know there is a difference.

 

NMS

 

Yes I have and it all looks good but I was just being careful.

 

Could you expand on that please

 

The code is probably the same then and it's just the calibration data that differs.

 

If you are suggesting he takes his car to them, he's from quite a few miles away

 

If you can post the stock bin file up somewhere I'll compare it to the bin file I have and see if it's only the calibration data that differs.

 

Tbh I doubt there are many who do have the stock software, best bet would be to try and find a standard chip imo, and read that.

The only real difference between a "red" and a "green" file is location 0FCBFh.
For a red file the loation is 00 (zero), for a green one it's 033h.
In the eprom this is location 3CBFh.
All maps and parameters are in the same place for both types.
There's also some info here: http://bigturbo.co.uk/main3.htm

 

Yeah, 6,291 miles to be fair! And it's still bloody snowing here, can you believe it?

 

Thanks. If I understand it correctly the binary file is the one I can get from the EPROM, as it is a Stage 3 and is going to be altered, and the definition file, (.xdf) is the one that shows the location of the maps and works in conjunction with the binary. I have put my standard chip in to the reader but it can't read a 27C64 chip (old technology). However when I put the new blank chip in, which is a 27SF512 it reads it fine and everything seems to be in the right place but as this .xdf file is for a green engine and mine is a red engine am I missing some maps or have I too many! Remember I am still learning just like you guys did when you first started.

 

Now this sounds like the info I need, I'm going to look at this, thank you Oldford.

 

27C64 chip? That was used on the rear wheel drive L1 and L6 ecu's.
An L8 should have a 27C128 chip.
Check what ecu you have here: http://bigturbo.co.uk/main1.htm

 

Try giving them a call, speak to Karl:

I definitely have an L8 but when I asked on here what number chip I had (as ex factory) no one replied so I went to another forum and that was what I was told so I'm sure you are correct.

 

I have tried contacting them by email and then by phone but with no luck as when there is 7 hrs difference in time it's difficult. I bought the chip from them originally.
